Viscosity and pH adjustments may need to be done, fragrances added, stability tests should be run (room temperature and heat), and microbial challenge tests should be done. Though they may need work, these formulas are unique and would be a hit with consumers looking for something different.
For instance, the first one is a shampoo that produces heat when applied to wet hair. To use, rinse hair, shake bottle and apply to wet hands, rub palms together and put on wet hair immediately. A warm feeling on the palms and head is felt. When the formulator mixes two parts water to one part shampoo, the temperature rises about 7°C.
|Sodium lauryl sulfate powder||8.00|
Procedure: With constant stirring, heat Part A in batch tank to 70-75°C. Heat Part B in separate container to 75°C and add to A. Cool to 55°C and add citric acid to pH 5.8. Perfume can be added at 50°C.
The above exothermic shampoo formula is expensive because it contains no water. A companion product could be the following:
|Quaternium 18 (and)isopropyl alcohol||3.5|
Procedure: With constant stirring, heat first two ingredients to 65°C, cool to 55°C and add the last ingredient.
The conditioner is applied to hair using the same procedure as the shampoo. One part of this with two parts of water results in an increase in temperature of 8°C.
Here is another hair conditioner with a gimmick. When applied to hair that has been washed, rinsed and towel dried, it will turn white when more water is added.
Novel Rinse-Off Conditioner
|POP-20 lanolin alcohol||25.0|
|POE-4 lauryl ether||25.0|
|Quaternium 18 (and)isopropyl alcohol||5.0|
|Alcohol SDA 40||30.0|
|Alcohol SDA 40||qs|
Procedure: With constant stirring, heat part A to 40°C. When uniform, add water at 40°C. Cool and qs with alcohol.
Below is a temporary hair-coloring product, which can be used on scalp hair or on facial hair (men only). It can be filled into a lipstick or similar applicator for use.
Wax Touch Up Hair Color
|Iron oxide umber||10|
|Iron oxide black||20|
Procedure: Disperse pigments in castor oil at room temperature, then heat to 75°C and add waxes. Mix and cool to 65°C. Fill into containers.
My last formula is a mouthwash containing vodka instead of alcohol. It could be a gift for someone who has everything or for a vodka lover.
The brand I used in this formula was Majorska 100 proof.
|Sodium saccharin 1%||2.0|
|Vodka (100 proof)||10.0|
Procedure: Mix the flavor and polysorbate together and add to water in the batch tank.
Add the remaining ingredients in the indicated order. Stir constantly. Cheers!
